Pressed Steel Castors are the most resourceful and generally used type of castor. The range is from 50 - 200mm diameter in 25mm augmentations with both soft & hard tread with a limit of up to 800kg per castor.
These castors usually have a swivel head bearing of either a single or double ball race construction. The balls run in tracks formed in the top plate and fork pressings that are then secured together by a heavy duty riveted steel kingpin.
Pressed Steel Castors are Ideal For Heavy Dynamic Loads and Towing applications or instances where shock loading may be integral to the subject.
